More specifically, substringing the value that SYS(2015) returns and trying to use the result as a valid file name. Only, the substrung result does NOT begin with an underscore or alpha and so is not a valid file name and so CRASHES AND BURNS gracelessly!!!

Yeah, use SYS(2015) NOT SUBSTR( SYS(2015...,) or if you use Substr(SYS...), prepend some known legal filename text like "_" or "tmp", etc. ... which you know now. :-)

Happened to me before too. :-) Two things I can think of. One, use the "Find" option in Windows Explorer to determine all files containing the string "SYS(2015)" and make corrections.

Or two, use my TableScan application in the UT Files section to scan all VFP table types for "SYS(2015)" to locate the files. Windows Explorer "Find" would probably be faster.
